Figure: (Top plot) $M_{\pi\pi}$ distribution of the $B^0\rightarrow h^{+}h^{'-}$ candidates selected applying the cuts reported in Tab.  and assigning the pion mass to both decay tracks. (Bottom plot) Same distribution obtained removing the cut on the B-isolation.

Figure: (Top plot) $\alpha$ distribution of the background events, defined as the events falling in the sidebands of the $M_{\pi\pi}$ distribution (4.600 GeV/c $^2< M_{\pi\pi} <$ 5.125 GeV/c$^2$ and 5.400 GeV/c $^2< M_{\pi\pi} <$ 5.800 GeV/c$^2$). (Bottom plot) transverse momentum distribution of the $B^0\rightarrow h^+h^{'-}$ signal reconstructed in data (crosses) and in Monte Carlo (yellow histogram), last bin contains overflows.

Figure: $M_{\pi\pi}$ versus $\alpha$ distributions of the six $B^0\rightarrow h^+h^{'-}$ decays.

Figure: $\alpha$ distributions of the six main $B^0\rightarrow h^+h^{'-}$ decays. All the plots have been made after applying all the analysis cuts.

Figure: Likelihood projections on the variable $M_{\pi\pi}$ used in the fit. Three choices of plots have been reported: only the sum of all contributions (left plot), the several contributions added together with different chromatic solutions (central and right plots).

Figure: Likelihood projections on the variable $\alpha$ used in the fit. Three choices of plots have been reported: only the sum of all contributions (left plot), the several contributions added together with different chromatic solutions (central and right plots).

Figure: Likelihood projection of the variable $\mathsf{ID1}$ used in the fit. Three choices of plots have been reported: only the sum of all contributions (left plot), the several contributions added together with different chromatic solutions (central and right plots).

Figure: Likelihood projection on the variable $\mathsf{ID2}$) used in the fit. Three choices of plots have been reported: only the sum of all contributions (left plot), the several contributions added together with different chromatic solutions (central and right plots).

Figure: Pull distributions of all the parameters determined by the fit. The distributions are obtained using 2000 toy Monte Carlo samples.

Figure: Distributions of the residuals of the $dE/dx$ measured for pions and kaons. Top plot is for positive charges, bottom plot is for negative charges.

Figure: (Top plot) Relative branching fraction $f_s BR(B_s\rightarrow K^+K^-)/f_d BR(B_d\rightarrow K^+\pi^-)$ drawn as a function of the average $B_s\rightarrow K^+K^-$ lifetime. The dashed line corresponds to a lifetime $\tau(B_s\rightarrow K^+K^-)= 1.45$ ps calculated under the following assumptions: 1. the CP-content of the $B_s\rightarrow K^+K^-$ mode is 100% CP-even, 2. $\Delta\Gamma_s/\Gamma_s = 0.12 \pm 0.06$, 3. $\Gamma_s=\Gamma_d$.
(Bottom plot) $M_{\pi\pi}$ distribution of the four $B^0\rightarrow h^+h^{'-}$ signals (particles and antiparticles are summed together) in the proportions measured by the fit.
